While the following description is given, centering on 3GPP LTE/LTE-Afor clarity, this is purely exemplary and thus should not be construedas limiting the present invention.

It should be noted that specific terms disclosed in the presentinvention are proposed for convenience of description and betterunderstanding of the present invention, and the use of these specificterms may be changed to other formats within the technical scope orspirit of the present invention.

The terms used in the specification are described.

-   -   HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement): this        represents an acknowledgment response to downlink transmission        (e.g. PDSCH or SPS release PDCCH), that is, an ACK/NACK/DTX        response (simply, ACK/NACK response, ACK/NACK). The ACK/NACK/DTX        response refers to ACK, NACK, DTX or NACK/DTX. HARQ-ACK for a        specific CC or HARQ-ACK of a specific CC refers to an ACK/NACK        response to a downlink signal (e.g. PDSCH) related to (e.g.        scheduled for) the corresponding CC. A PDSCH can be replaced by        a transport block (TB) or a codeword.    -   PDSCH: this corresponds to a DL grant PDCCH. The PDSCH is used        interchangeably with a PDSCH w/PDCCH in the specification.    -   SPS release PDCCH: this refers to a PDCCH indicating SPS        release. A UE performs uplink feedback of ACK/NACK information        about an SPS release PDCCH.    -   SPS PDSCH: this is a PDSCH transmitted on DL using a resource        semi-statically set according to SPS. The SPS PDSCH has no DL        grant PDCCH corresponding thereto. The SPS PDSCH is used        interchangeably with a PDSCH w/o PDCCH in the specification.    -   PUCCH index: This corresponds to a PUCCH resource. The PUCCH        index represents a PUCCH resource index, for example. The PUCCH        resource index is mapped to at least one of an orthogonal cover        (OC), a cyclic shift (CS) and a PRB.    -   ARI (ACK/NACK resource indicator): This is used to indicate a        PUCCH resource. For example, the ARI can be used to indicate a        resource change value (e.g. offset) with respect to a specific        PUCCH resource (configured by a higher layer). Furthermore, the        ARI can be used to indicate a specific PUCCH resource (group)        index in a PUCCH resource (group) set (configured by a higher        layer). The ARI can be included in a TPC field of a PDCCH        corresponding to a PDSCH on an SCC. PUCCH power control is        performed in a TPC field in a PDCCH (that is, PDCCH        corresponding to a PDSCH on a PCC) that schedules the PCC. The        ARI can be included in a TPC field of a PDCCH other than a PDCCH        that has a downlink assignment index (DAI) initial value and        schedules a specific cell (e.g. PCell). The ARI is used with a        HARQ-ACK resource indication value.    -   DAI (downlink assignment index): this is included in DCI        transmitted through a PDCCH. The DAI can indicate an order value        or counter value of a PDCCH. A value indicated by a DAI field of        a DL grant PDCCH is called a DL DAI and a value indicated by a        DAI field of a UL grant PDCCH is called a UL DAI for        convenience.    -   Implicit PUCCH resource: This represents a PUCCH resource/index        linked to the smallest CCE index of a PDCCH that schedules a PCC        (refer to Equation 1).    -   Explicit PUCCH resource: This can be indicated using the ARI.    -   PDCCH scheduling CC: This represents a PDCCH that schedules a        PDSCH on a CC, that is, a PDCCH corresponding to a PDSCH on the        CC.    -   PCell PDCCH: This represents a PDCCH that schedules a PCell.        That is, the PCell PDCCH indicates a PDCCH corresponding to a        PDSCH on the PCell. When it is assumed that cross-carrier        scheduling is not allowed for the PCell, the PCell PDCCH is        transmitted only on the PCell.    -   SCell PDCCH: This represents a PDCCH that schedules an SCell.        That is, the SCell PDCCH indicates a PDCCH corresponding to a        PDSCH on the SCell. When cross-carrier scheduling is allowed for        the SCell, the SCell PDCCH can be transmitted on the PCC. On the        other hand, when cross-carrier scheduling is not allowed for the        SCell, the SCell PDCCH is transmitted only on the SCell.

Cross-carrier scheduling: This represents an operation ofscheduling/transmitting a PDCCH that schedules a first cell through asecond cell different from the first cell.

Non-cross-carrier scheduling: This represents an operation ofscheduling/transmitting a PDCCH that schedules a cell through the cell.

In a wireless communication system, a UE receives information from a BSon downlink (DL) and transmits information to the BS on uplink (UL).Information transmitted/received between the UE and BS includes data andvarious types of control information, and various physical channels arepresent according to type/purpose of information transmitted/receivedbetween the UE and BS.

FIG. 1 illustrates physical channels used in a 3GPP LTE system and asignal transmission method using the same.

When powered on or when a UE initially enters a cell, the UE performsinitial cell search involving synchronization with a BS in step S101.For initial cell search, the UE synchronizes with the BS and acquireinformation such as a cell Identifier (ID) by receiving a primarysynchronization channel (P-SCH) and a secondary synchronization channel(S-SCH) from the BS. Then the UE may receive broadcast information fromthe cell on a physical broadcast channel (PBCH). In the mean time, theUE may check a downlink channel status by receiving a downlink referencesignal (DL RS) during initial cell search.

After initial cell search, the UE may acquire more specific systeminformation by receiving a physical downlink control channel (PDCCH) andreceiving a physical downlink shared channel (PDSCH) based oninformation of the PDCCH in step S102.

The UE may perform a random access procedure to access the BS in stepsS103 to S106. For random access, the UE may transmit a preamble to theBS on a physical random access channel (PRACH) (S103) and receive aresponse message for preamble on a PDCCH and a PDSCH corresponding tothe PDCCH (S104). In the case of contention-based random access, the UEmay perform a contention resolution procedure by further transmittingthe PRACH (S105) and receiving a PDCCH and a PDSCH corresponding to thePDCCH (S106).

After the foregoing procedure, the UE may receive a PDCCH/PDSCH (S107)and transmit a physical uplink shared channel (PUSCH)/physical uplinkcontrol channel (PUCCH) (S108), as a general downlink/uplink signaltransmission procedure. Here, control information transmitted from theUE to the BS is called uplink control information (UCI). The UCI mayinclude a hybrid automatic repeat and request (HARQ)acknowledgement(ACK)/negative-ACK (HARQ ACK/NACK) signal, a schedulingrequest (SR), channel state information (CSI), etc. The CSI includes achannel quality indicator (CQI), a precoding matrix index (PMI), a rankindicator (RI), etc. While the UCI is transmitted through a PUCCH ingeneral, it may be transmitted through a PUSCH when control informationand traffic data need to be simultaneously transmitted. The UCI may beaperiodically transmitted through a PUSCH at the request/instruction ofa network.

FIG. 2 illustrates a radio frame structure. In a cellular OFDM wirelesspacket communication system, uplink/downlink data packet transmission isperformed on a subframe-by-subframe basis. A subframe is defined as apredetermined time interval including a plurality of OFDM symbols. 3GPPLTE supports a type-1 radio frame structure applicable to FDD (FrequencyDivision Duplex) and a type-2 radio frame structure applicable to TDD(Time Division Duplex).

FIG. 2(a) illustrates a type-1 radio frame structure. A downlinksubframe includes 10 subframes each of which includes 2 slots in thetime domain. A time for transmitting a subframe is defined as atransmission time interval (TTI). For example, each subframe has alength of 1 ms and each slot has a length of 0.5 ms. A slot includes aplurality of OFDM symbols in the time domain and includes a plurality ofresource blocks (RBs) in the frequency domain. Since downlink uses OFDMin 3GPP LTE, an OFDM symbol represents a symbol period. The OFDM symbolmay be called an SC-FDMA symbol or symbol period. An RB as a resourceallocation unit may include a plurality of consecutive subcarriers inone slot.

The number of OFDM symbols included in one slot may depend on cyclicprefix (CP) configuration. CPs include an extended CP and a normal CP.When an OFDM symbol is configured with the normal CP, for example, thenumber of OFDM symbols included in one slot may be 7. When an OFDMsymbol is configured with the extended CP, the length of one OFDM symbolincreases, and thus the number of OFDM symbols included in one slot issmaller than that in case of the normal CP. In case of the extended CP,the number of OFDM symbols allocated to one slot may be 6. When achannel state is unstable, such as a case in which a UE moves at a highspeed, the extended CP can be used to reduce inter-symbol interference.

When the normal CP is used, one subframe includes 14 OFDM symbols sinceone slot has 7 OFDM symbols. The first three OFDM symbols at most ineach subframe can be allocated to a PDCCH and the remaining OFDM symbolscan be allocated to a PDSCH.

FIG. 2(b) illustrates a type-2 radio frame structure. The type-2 radioframe includes 2 half frames. Each half frame includes 5 subframes. Asubframe may be one of a downlink subframe, an uplink subframe and aspecial subframe. The special subframe can be used as a downlinksubframe or an uplink subframe according to TDD configuration. Thespecial subframe includes a downlink pilot time slot (DwPTS), a guardperiod (GP), and an uplink pilot time slot (UpPTS). The DwPTS is usedfor initial cell search, synchronization or channel estimation in a UE.The UpPTS is used for channel estimation in a BS and UL transmissionsynchronization acquisition in a UE. The GP eliminates UL interferencecaused by multi-path delay of a DL signal between a UL and a DL.

Table 1 shows UL-DL configurations of subframes in a radio frame in theTDD mode.

In Table 1, D denotes a downlink subframe, U denotes an uplink subframeand S denotes a special subframe. The special subframe includes DwPTS(Downlink Pilot TimeSlot), GP (Guard Period), and UpPTS (Uplink PilotTimeSlot). DwPTS is a period reserved for downlink transmission andUpPTS is a period reserved for uplink transmission.

The radio frame structure is merely exemplary and the number ofsubframes included in the radio frame, the number of slots included in asubframe, and the number of symbols included in a slot can be vary.

FIG. 3 illustrates a resource grid of a downlink slot.

Referring to FIG. 3, a downlink slot includes a plurality of OFDMsymbols in the time domain. One downlink slot may include 7(6) OFDMsymbols, and one resource block (RB) may include 12 subcarriers in thefrequency domain. Each element on the resource grid is referred to as aresource element (RE). One RB includes 12×7(6) REs. The number N_(RB) ofRBs included in the downlink slot depends on a downlink transmitbandwidth. The structure of an uplink slot may be same as that of thedownlink slot except that OFDM symbols by replaced by SC-FDMA symbols.

FIG. 4 illustrates a downlink subframe structure.

Referring to FIG. 4, a maximum of three (four) OFDM symbols located in afront portion of a first slot within a subframe correspond to a controlregion to which a control channel is allocated. The remaining OFDMsymbols correspond to a data region to which a physical downlink sharedchancel (PDSCH) is allocated. Examples of downlink control channels usedin LTE include a physical control format indicator channel (PCFICH), aphysical downlink control channel (PDCCH), a physical hybrid ARQindicator channel (PHICH), etc. The PCFICH is transmitted at a firstOFDM symbol of a subframe and carries information regarding the numberof OFDM symbols used for transmission of control channels within thesubframe. The PHICH is a response of uplink transmission and carries anHARQ acknowledgment (ACK)/negative-acknowledgment (NACK) signal.

Control information transmitted through the PDCCH is referred to asdownlink control information (DCI). Formats 0, 3, 3A and 4 for uplinkand formats 1, 1A, 1B, 1C, 1D, 2, 2A, 2B and 2C for downlink are definedas DCI formats. The DCI formats selectively include information such ashopping flag, RB allocation, MCS (Modulation Coding Scheme), RV(Redundancy Version), NDI (New Data Indicator), TPC (Transmit PowerControl), cyclic shift DM RS (Demodulation Reference Signal), CQI(Channel Quality Information) request, HARQ process number, TPMI(Transmitted Precoding Matrix Indicator), PMI (Precoding MatrixIndicator) confirmation according as necessary.

A PDCCH may carry a transport format and a resource allocation of adownlink shared channel (DL-SCH), resource allocation information of anuplink shared channel (UL-SCH), paging information on a paging channel(PCH), system information on the DL-SCH, information on resourceallocation of an upper-layer control message such as a random accessresponse transmitted on the PDSCH, a set of Tx power control commands onindividual UEs within an arbitrary UE group, a Tx power control command,information on activation of a voice over IP (VoIP), etc. A plurality ofPDCCHs can be transmitted within a control region. The UE can monitorthe plurality of PDCCHs. The PDCCH is transmitted on an aggregation ofone or several consecutive control channel elements (CCEs). The CCE is alogical allocation unit used to provide the PDCCH with a coding ratebased on a state of a radio channel. The CCE corresponds to a pluralityof resource element groups (REGs). A format of the PDCCH and the numberof bits of the available PDCCH are determined by the number of CCEs. TheBS determines a PDCCH format according to DCI to be transmitted to theUE, and attaches a cyclic redundancy check (CRC) to control information.The CRC is masked with a unique identifier (referred to as a radionetwork temporary identifier (RNTI)) according to an owner or usage ofthe PDCCH. If the PDCCH is for a specific UE, a unique identifier (e.g.,cell-RNTI (C-RNTI)) of the UE may be masked to the CRC. Alternatively,if the PDCCH is for a paging message, a paging identifier (e.g.,paging-RNTI (P-RNTI)) may be masked to the CRC. If the PDCCH is forsystem information (more specifically, a system information block(SIB)), a system information RNTI (SI-RNTI) may be masked to the CRC.When the PDCCH is for a random access response, a random access-RNTI(RA-RNTI) may be masked to the CRC.

FIG. 5 illustrates an uplink subframe structure used in LTE.

Referring to FIG. 5, an uplink subframe includes a plurality of (e.g. 2)slots. A slot may include different numbers of SC-FDMA symbols accordingto CP lengths. The uplink subframe is divided into a control region anda data region in the frequency domain. The data region is allocated witha PUSCH and used to carry a data signal such as audio data. The controlregion is allocated a PUCCH and used to carry uplink control information(UCI). The PUCCH includes an RB pair located at both ends of the dataregion in the frequency domain and hopped in a slot boundary.

The PUCCH can be used to transmit the following control information.

-   -   SR (scheduling request): This is information used to request a        UL-SCH resource and is transmitted using On-Off Keying (OOK)        scheme.    -   HARQ ACK/NACK: This is a response signal to a downlink data        packet on a PDSCH and indicates whether the downlink data packet        has been successfully received. A 1-bit ACK/NACK signal is        transmitted as a response to a single downlink codeword and a        2-bit ACK/NACK signal is transmitted as a response to two        downlink codewords.    -   CQI (channel quality indicator): This is feedback information        about a downlink channel. Feedback information regarding        Multiple Input Multiple Output (MIMO) includes Rank Indicator        (RI) and Precoding Matrix Indicator (PMI). 20 bits are used for        each subframe.

The quantity of control information (UCI) that a UE can transmit througha subframe depends on the number of SC-FDMA symbols available forcontrol information transmission. The SC-FDMA symbols available forcontrol information transmission correspond to SC-FDMA symbols otherthan SC-FDMA symbols of the subframe, which are used for referencesignal transmission. In the case of a subframe in which a SoundingReference Signal (SRS) is configured, the last SC-FDMA symbol of thesubframe is excluded from the SC-FDMA symbols available for controlinformation transmission. A reference signal is used to detect coherenceof the PUCCH. The PUCCH supports 7 formats according to informationtransmitted thereon.

Table 2 shows the mapping relationship between PUCCH formats and UCI inLTE.

TABLE 2 PUCCH format UCI (Uplink Control Information) Format 1 SR(Scheduling Request) (non-modulated waveform) Format 1a 1-bit HARQACK/NACK (SR exist/non-exist) Format 1b 2-bit HARQ ACK/NACK (SRexist/non-exist) Format 2 CQI (20 coded bits) Format 2 CQI and 1- or2-bit HARQ ACK/NACK (20 bits) (corresponding to only extended CP) Format2a CQI and 1-bit HARQ ACK/NACK (20 + 1 coded bits) Format 2b CQI and2-bit HARQ ACK/NACK (20 + 2 coded bits) Format 3 HARQ ACK/NACK + SR (48bits) (LTE-A)

FIGS. 6 and 7 illustrate slot level structures of PUCCH formats 1a/1b.FIG. 6 shows normal CP case and FIG. 7 shows extended CP case. The PUCCHformats 1a/1b are used for ACK/NACK transmission. In the case of normalCP, SC-FDMA symbols #2, #3 and #4 are used for DMRS transmission. In thecase of extended CP, SC-FDMA symbols #2 and #3 are used for DMRStransmission. Accordingly, 4 SC-FDMA symbols in a slot are used forACK/NACK transmission. PUCCH format 1a/1b is called PUCCH format 1 inthe specification unless otherwise mentioned.

Referring to FIGS. 6 and 7, 1-bit [b(0)] and 2-bit [b(0)b(1)] ACK/NACKinformation are modulated according to BPSK (binary phase shift keying)and QPSK (quadrature phase shift keying) modulation schemesrespectively, to generate one ACK/NACK modulation symbol d₀. Each bit[b(i), i=0, 1] of the ACK/NACK information indicates a HARQ response toa corresponding DL transport block, corresponds to 1 in the case ofpositive ACK and corresponds to 0 in case of negative ACK (NACK). Table3 shows a modulation table defined for PUCCH formats 1a and 1b inLTE/LTE-A.

TABLE 3 PUCCH format b(0), . . . , b(M_(bit) − 1) d(0) 1a 0 1 1 −1   1b00 1 01 −j   10 j 11 −1  

In the case of PUCCH format 1, the same control information is repeatedon a slot basis in a subframe. UEs transmit ACK/NACK signals throughdifferent resources configured of different cyclic shifts (CSs)(frequency domain codes) of a CG-CAZAC (computer-generated constantamplitude zero auto correlation) sequence and orthogonal covers ororthogonal cover codes (OCs or OCCs) (time domain spreading codes). TheOC includes a Walsh/DFT orthogonal code, for example. When the number ofCSs is 6 and the number of OCs is 3, 18 UEs can be multiplexed in thesame PRB on the basis of a single antenna. An orthogonal sequence w0,w1, w2, w3 can be applied in a time domain (after FFT) or a frequencydomain (before FFT).

RSs transmitted from different UEs are multiplexed using the same methodas is used to multiplex UCI. The number of cyclic shifts supported bySC-FDMA symbols for PUCCH ACK/NACK RB can be configured by cell-specifichigher layer signaling parameter Δ_(shift) ^(PUCCH). Δ_(shift)^(PUCCH)ε{1, 2, 3} represents that shift values are 12, 6 and 4,respectively. In time-domain CDM, the number of spreading codes actuallyused for ACK/NACK can be limited by the number of RS symbols becausemultiplexing capacity of RS symbols is less than that of UCI symbols dueto a smaller number of RS symbols.

FIG. 8 illustrates an example of determining PUCCH resources forACK/NACK. In LTE, a plurality of PUCCH resources for ACK/NACK are sharedby a plurality of UEs in a cell every time the UEs need the PUCCHresources rather than allocated to UEs in advance. Specifically, a PUCCHresource used by a UE to transmit an ACK/NACK signal corresponds to aPDCCH on which scheduling information on DL data involving the ACK/NACKsignal is delivered. A PDCCH transmitted in a DL subframe to a UE isconfigured with one or more control channel elements (CCEs), andACK/NACK can be transmitted through a PUCCH resource corresponding to aspecific one (e.g. first CCE) of the CCEs constituting the PDCCH.

Referring to FIG. 8, each block in a downlink component carrier (DL CC)represents a CCE and each block in an uplink component carrier (UL CC)indicates a PUCCH resource. Each PUCCH index corresponds to a PUCCHresource for ACK/NACK. If information on a PDSCH is delivered on a PDCCHcomposed of CCEs #4, #5 and #6, as shown in FIG. 8, a UE transmits anACK/NACK signal on PUCCH #4 corresponding to CCE #4, the first CCE ofthe PDCCH. FIG. 8 illustrates a case in which maximum M PUCCHs arepresent in the UL CC when maximum N CCEs exist in the DL CC. Though Ncan equal M, N may differ from M and CCEs are mapped to PUCCHs in anoverlapped manner.

Specifically, a PUCCH resource index in LTE is determined as follows.n ⁽¹⁾ _(PUCCH) =n _(CCE) +N ⁽¹⁾ _(PUCCH)  [Equation 1]

Here, n⁽¹⁾ _(PUCCH) represents a resource index of PUCCH format 1 forACK/NACK/DTX transmission, N⁽¹⁾ _(PUCCH) denotes a signaling valuereceived from a higher layer, and n_(CCE) denotes the smallest value ofCCE indexes used for PDCCH transmission. A cyclic shift, an orthogonalcover code (or orthogonal spreading code) and a PRB for PUCCH format 1are obtained from n⁽¹⁾ _(PUCCH).

When an LTE system operates in TDD, a UE transmits a single multiplexedACK/NACK signal for a plurality of data units (e.g. PDSCHs, SPS releasePDCCHs, etc.) received through different subframes. Methods oftransmitting ACK/NACK for a plurality of data units include thefollowing.

1) ACK/NACK bundling: ACK/NACK bits for a plurality of data units arecombined according to a logical AND operation. For example, uponsuccessful decoding of all data units, an Rx node (e.g. UE) transmitsACK signals. If any of data units has not been decoded (detected), theRx node transmits a NACK signal or no signal.

2) Channel selection: Upon reception of a plurality of PDSCHs, a UEoccupies a plurality of PUCCH resources for ACK/NACK transmission.ACK/NACK responses to the plurality of data units are discriminatedaccording to combinations of PUCCH resources used for ACK/NACKtransmission and transmitted ACK/NACK information (e.g. bit values).This is also referred to as ACK/NACK (or PUCCH) selection.

Channel selection will now be described in detail. When the UE receivesa plurality of DL data according to the channel selection scheme, the UEoccupies a plurality of UL physical channels in order to transmit amultiplexed ACK/NACK signal. For example, when the UE receives aplurality of PDSCHs, the UE can occupy the same number of PUCCHs as thePDSCHs using a specific CCE of a PDCCH which indicates each PDSCH. Inthis case, the UE can transmit a multiplexed ACK/NACK signal usingcombination of which one of the occupied PUCCHs is selected andmodulated/coded results applied to the selected PUCCH.

Table 4 shows a mapping table for channel selection, defined inLTE/LTE-A

In Table 4, HARQ-ACK(i) indicates the HARQ ACK/NACK/DTX result of ani-th data unit (0≦i≦3). Results of HARQ ACK/NACK/DTX include ACK, NACK,DTX and NACK/DTX. NACK/DTX represents NACK or DTX. ACK represents that atransport block (equivalent to a code block) transmitted on a PDSCH hasbeen successfully decoded whereas NACK represents that the transportblock has not been successfully decode. DTX represents PDCCH detectionfailure. Maximum 4 PUCCH resources (i.e., n⁽¹⁾ _(PUCCH,0) to n⁽¹⁾_(PUCCH,3)) can be occupied for each data unit. The multiplexed ACK/NACKsignal is transmitted through one PUCCH resource selected from theoccupied PUCCH resources. In Table 4, n⁽¹⁾ _(PUCCH,i) represents a PUCCHresource actually used for ACK/NACK transmission, and b(0)b(1) indicatestwo bits transmitted through the selected PUCCH resource, which aremodulated using QPSK. For example, when the UE has decoded 4 data unitssuccessfully, the UE transits bits (1, 1) to a BS through a PUCCHresource linked with n⁽¹⁾ _(PUCCH,1). Since combinations of PUCCHresources and QPSK symbols cannot represent all available ACK/NACKsuppositions, NACK and DTX are coupled except some cases (NACK/DTX,N/D).

FIG. 9 illustrates a carrier aggregation (CA) communication system.LTE-A aggregates a plurality of UL/DL frequency blocks to support awider UL/DL bandwidth in order to use a wider frequency band.

Referring to FIG. 9, a plurality of UL/DL component carriers (CCs) canbe aggregated to support a wider UL/DL bandwidth. The CCs may becontiguous or non-contiguous in the frequency domain. Bandwidths of theCCs can be independently determined. Asymmetrical CA in which the numberof UL CCs is different from the number of DL CCs can be implemented. Forexample, when there are two DL CCs and one UL CC, the DL CCs cancorrespond to the UL CC in the ratio of 2:1. A DL CC/UL CC link can befixed or semi-statically configured in the system. Even if the systembandwidth is configured with N CCs, a frequency band that a specific UEcan monitor/receive can be limited to M (<N) CCs. Various parameterswith respect to CA can be set cell-specifically, UE-group-specifically,or UE-specifically. Control information may be transmitted/received onlythrough a specific CC. This specific CC can be referred to as a primaryCC (PCC) (or anchor CC) and other CCs can be referred to as secondaryCCs (SCCs).

In LTE-A, the concept of a cell is used to manage radio resources. Acell is defined as a combination of downlink resources and uplinkresources. Yet, the uplink resources are not mandatory. Therefore, acell may be composed of downlink resources only or both downlinkresources and uplink resources. The linkage between the carrierfrequencies (or DL CCs) of downlink resources and the carrierfrequencies (or UL CCs) of uplink resources may be indicated by systeminformation. A cell operating in primary frequency resources (or a PCC)may be referred to as a primary cell (PCell) and a cell operating insecondary frequency resources (or an SCC) may be referred to as asecondary cell (SCell). The PCell is used for a UE to establish aninitial connection or re-establish a connection. The PCell may refer toa cell indicated during handover. The SCell may be configured after anRRC connection is established and may be used to provide additionalradio resources. The PCell and the SCell may collectively be referred toas a serving cell. Accordingly, a single serving cell composed of aPCell only exists for a UE in an RRC_CONNECTED state, for which CA isnot set or which does not support CA. On the other hand, one or moreserving cells exist, including a PCell and entire SCells, for a UE in anRRC_CONNECTED state, for which CA is set. For CA, a network mayconfigure one or more SCells in addition to an initially configuredPCell, for a UE supporting CA during connection setup after an initialsecurity activation operation is initiated.

When cross-carrier scheduling (or cross-CC scheduling) is applied, aPDCCH for downlink allocation can be transmitted on DL CC #0 and a PDSCHcorresponding thereto can be transmitted on DL CC #2. For cross-CCscheduling, introduction of a carrier indicator field (CIF) can beconsidered. Presence or absence of the CIF in a PDCCH can be determinedby higher layer signaling (e.g. RRC signaling) semi-statically andUE-specifically (or UE group-specifically). The baseline of PDCCHtransmission is summarized as follows.

-   -   CIF disabled: a PDCCH on a DL CC is used to allocate a PDSCH        resource on the same DL CC or a PUSCH resource on a linked UL        CC.    -   CIF enabled: a PDCCH on a DL CC can be used to allocate a PDSCH        or PUSCH resource on a specific DL/UL CC from among a plurality        of aggregated DL/UL CCs using the CIF.

When the CIF is present, the BS can allocate a PDCCH monitoring DL CC toreduce BD complexity of the UE. The PDCCH monitoring DL CC set includesone or more DL CCs as parts of aggregated DL CCs and the UEdetects/decodes a PDCCH only on the corresponding DL CCs. That is, whenthe BS schedules a PDSCH/PUSCH for the UE, a PDCCH is transmitted onlythrough the PDCCH monitoring DL CC set. The PDCCH monitoring DL CC setcan be set in a UE-specific, UE-group-specific or cell-specific manner.The term “PDCCH monitoring DL CC” can be replaced by the terms such as“monitoring carrier” and “monitoring cell”. The term “CC” aggregated forthe UE can be replaced by the terms such as “serving CC”, “servingcarrier” and “serving cell”.

FIG. 10 illustrates scheduling when a plurality of carriers isaggregated. It is assumed that 3 DL CCs are aggregated and DL CC A isset to a PDCCH monitoring DL CC. DL CC A, DL CC B and DL CC C can becalled serving CCs, serving carriers, serving cells, etc. In case of CIFdisabled, a DL CC can transmit only a PDCCH that schedules a PDSCHcorresponding to the DL CC without a CIF according to LTE PDCCH rule.When the CIF is enabled, DL CC A (monitoring DL CC) can transmit notonly a PDCCH that schedules the PDSCH corresponding to the DL CC A butalso PDCCHs that schedule PDSCHs of other DL CCs using the CIF. In thiscase, A PDCCH is not transmitted in DL CC B/C which is not set to aPDCCH monitoring DL CC.

A description will be given of a method for transmitting ACK/NACK usingchannel selection in a CA system. For this method, PUCCH formats 1a/1b,preferably, PUCCH format 1b can be used. Channel selection using PUCCHformat 1b (simply, PUCCH format 1b/channel selection) is used for bothFDD and TDD.

FDD channel selection is described first. When a plurality of (e.g. 2)serving cells are configured and PUCCH format 1b/channel selection isset, a UE transmits b(0)b(1) through a PUCCH resource selected from APUCCH resources (n_(PUCCH,i) ⁽¹⁾, 0≦i≦A−1 and Aε[2,3,4]) according toHARQ-ACK(j). HARQ-ACK(j) represents an ACK/NACK/DTX response to atransport block related to serving cell c or an SPS release PDCCH.

Table 5 shows the relationship of HARQ-ACK(j), serving cells andtransport blocks.

A PUCCH resources (n_(PUCCH,i) ⁽¹⁾, 0≦i≦A−1 and Aε[2,3,4]) aredetermined in the following manner.

-   -   PUCCH resource n_(PUCCH,i) ⁽¹⁾ is given by n_(PUCCH,i)        ⁽¹⁾=n_(CCE)+N_(PUCCH) ⁽¹⁾ for a PDSCH indicated by a PDCCH        detected from subframe n−4 on a PCell or a PDCCH indicating        downlink SPS release, detected from subframe n−4 on the PCell.        When the transmission mode of the PCell supports two transport        blocks, an additional PUCCH resource n_(PUCCH,i+1) ⁽¹⁾ is given        by n_(PUCCH,i+1) ⁽¹⁾=n_(CCE)+1+N_(PUCCH) ⁽¹⁾. Here, n_(CCE)        represents the first CCE used for transmission of the        corresponding PDCCH and N_(PUCCH) ⁽¹⁾ is set by a higher layer.    -   For transmission of a PDSCH (without a PDCCH detected from        subframe n−4) on the PCell, PUCCH resource n_(PUCCH,i) ⁽¹⁾ is        provided by a higher layer. When the transmission mode of the        PCell supports two transport blocks, an additional PUCCH        resource n_(PUCCH,i+1) ⁽¹⁾ is given by n_(PUCCH,i+1)        ⁽¹⁾=n_(CCE)+1+N_(PUCCH) ⁽¹⁾.    -   For a PDSCH indicated by a PDCCH detected from subframe n−4 of        an SCell, n_(PUCCH,i) ⁽¹⁾ and n_(PUCCH,i+1) ⁽¹⁾ (in the case of        transmission mode supporting two transport blocks) are        determined according to higher layer configuration. A TPC field        vale for a PUCCH in the DCI format of the corresponding PDCCH is        used to indicate one of 4 PUCCH resource values configured by a        higher layer (ARI). The indicated PUCCH resource value is mapped        to two PUCCH resources n_(PUCCH,i) ⁽¹⁾ and n_(PUCCH,i+1) ⁽¹⁾ if        the transmission mode of the SCell supports two transport blocks        and mapped to one PUCCH resource n_(PUCCH,i) ⁽¹⁾ if not.

In the case of a TDD based CA system, A/N signals for M DL subframes (DLbundling window) are transmitted through one UL subframe.

A description will be given of a transmit diversity (TxD) scheme forchannel selection.

Referring to FIG. 11, SORTD repeatedly transmits the same information byadditionally using as many PUCCH resources used (or reserved) forchannel selection as the number of transmit (Tx) antennas (antennaports). For example, if 4 PUCCH resources are used (or reserved) forchannel selection during transmission using a single Tx antenna, 8 PUCCHresources are used (or reserved) during transmission using 2 Txantennas. In one embodiment, the same channel selector (or mappingtable) is applied to two antenna ports and the same information s_n istransmitted through selected channels, as described in FIG. 11. Here,s_n can represent a modulation symbol (or bit value). While the presentembodiment illustrates 2Tx SORTD, SORTD for transmission using three ormore Tx antennas is applicable in the same manner.

Tables 12, 13 and 14 show application of SORTD in the case of 2-bit,3-bit and 4-bit ACK/NACK information. In the tables, ChX denotes PUCCHchannel X/resource X and may be replaced by n_(PUCCH,X) ⁽¹⁾.

The number of (orthogonal) resources used for N_(TX)(SORTD can berepresented by N_(TX)·M (N_(TX) being the number of Tx antenna ports, Mbeing the number of (orthogonal) resources used for 1 Tx channelselection).

Accordingly, if Table 14 is applied to the example of FIG. 11 and A/Nstate is NANA, channel selection can be applied to the two antenna portsas follows.

-   -   In the case of antenna port #0, Ch1 is selected to transmit        −j(s_n).    -   In the case of antenna port #1, Ch5 is selected to transmit        −j(s_n).

Table 15 shows A/N performance of 1Tx transmission and 2Tx SORTDaccording to Tables 12, 13 and 14.

Here, required SNR denotes a maximum SNR that satisfies the followingconditions. Higher performance is achieved as the required SNRdecreases.

-   -   DTX→ACK probability: 1% or lower (i.e. Pr(D→A)≦1%)    -   ACK misdetection (ACK→NACK, ACK→DTX) probability: 1% or lower        (i.e. Pr(A→N/D)≦1%)    -   NACK→ACK probability: 0.1% or lower (i.e. Pr(N→A)≦0.1%)

Referring to FIG. 15, SORTD can achieve a maximum SNR gain of 1.28.

The number of available PUCCH resources is associated with the number ofUEs multiplexed in one PRB. Accordingly, when 2Tx SORTD is applied toPUCCH format 1b, the number of PUCCH resources available in one PRB isreduced by half, resulting in 50% reduction in multiplexing capacity.For example, when Δ_(shift) ^(PUCCH)=2, a maximum of eighteen 1Tx UEscan be multiplexed in one PRB whereas a maximum of nine 2Tx SORTD UEscan be multiplexed in one PRB. When Δ_(shift) ^(PUCCH)=2 in PUCCH format1b/channel selection and 4-bit A/N is transmitted, multiplexing capacityof 1Tx UEs is 4.5 (=18/4) in one PRB whereas multiplexing capacity of2Tx SORTD UEs is 2.25 (=9/4) in one PRB. If SORTD is used fortransmission using three or more Tx antennas, resource overheadincreases in proportion to the number of antennas. That is, trade-off ispresent between diversity gain and multiplexing capacity in SORTD.

Embodiment

The present invention proposes a transmit diversity scheme for channelselection, which solves the above-described problem with respect tomultiplexing and achieves performance corresponding to SORTD, andresource allocation for the same. While a case in which two antennas (orantenna ports) are used is described in the following for facilitationof description, the present invention is applicable to a case in whichthree or more antennas (or antenna ports) are used. In addition, whilechannel selection for 3(4)-bit A/N information transmission will bedescribed in the following for convenience, the present invention can begeneralized as channel selection for N-bit A/N information transmission.Here, N is a positive integer.

In the case of transmission using at least two antennas (or antennaports), the transmit diversity scheme according to the present inventionincludes channel selection respectively performed on a reference signal(RS) and data, which is extended from conventional channel selectioncarried out on a pair of an RS and data (i.e. UCI, e.g. A/N). That is,according to a conventional method, a single PUCCH resource indexn_(PUCCH) ⁽¹⁾ is selected according to channel selection (refer toTables 4 and 6 to 14) and both resources (e.g. PRB, CS and OCC) for RStransmission and resources (e.g. PRB, CS and OCC) for data transmissionare inferred from the PUCCH resource index n_(PUCCH) ⁽¹⁾. In this case,the RS transmission resources and data transmission resources, obtainedfrom the PUCCH resource index n_(PUCCH) ⁽¹⁾, are identical to eachother. That is, the PRB, CS and OCC used for RS transmission areidentical to the PRB, CS and OCC used for data transmission. The presentinvention independently selects a PUCCH resource index (n_(PUCCH,RS)⁽¹⁾) for an RS and a PUCCH resource index (n_(PUCCH,DATA) ⁽¹⁾) for dataduring channel selection and respectively derives transmission resources(e.g. PRB, CS and OCC) from the PUCCH resource indices. Accordingly, atleast one of the PRB, CS and OCC used for RS transmission is differentfrom the corresponding one of the PRB, CS and OCC used for datatransmission. For convenience, a method of independently performingchannel selection on the RS and data is referred to as RS-data separatechannel selection. According to RS-data separate channel selection,considerable performance can be achieved using a minimum mean squareerror (MMSE) receiver or the like even when selected channels arelocated in different PRBs although optimum performance is achieved whenselected channels are positioned in the same PRB.

FIG. 12 illustrates transmit diversity scheme according to an embodimentof the present invention. Basics of the transmit diversity scheme issimilar to those illustrated in FIG. 11. However, the transmit diversityscheme according to the present invention pairs an RS and data for anantenna port during channel selection and separates the RS from data fora different antenna port during channel selection, distinguished fromSORTD illustrated in FIG. 11. Here, the data represents UCI, forexample, A/N. For the proposed scheme, antenna port #0 can useconventional mapping tables (e.g. Tables 4 and 6 to 14) defined forchannel selection performed on a pair of an RS and data for singleantenna transmission whereas antenna port #1 can use mapping tablesdefined for channel selection respectively performed on the RS and data.The same modulation symbol (e.g. QAM or PSK symbol) value may betransmitted through data parts according to channel selection for therespective antenna ports.

Tables 16, 17 and 18 are mapping tables according to an embodiment ofthe present invention, which show implementation of transmit diversityusing 4 PUCCHs during channel selection for 4-bit A/N transmission.Numbers in the tables denote complex values modulated to RS/datachannels. For an A/N state, different complex values may be transmittedthrough respective antennas (antenna ports). However, the presentembodiment illustrates a case in which the same complex value istransmitted through the antennas.

Table 16 shows a case in which an RS channel corresponding to antennaport #1 is selected by “(RS channel selected for antenna port #0+2) mod4” and a data channel corresponding to antenna port #1 is selected by“RS channel of antenna port#0+(−1)^((RS channel number of antenna port #1))”. Table 17 is amodification of Table 16.

While Tables 16 and 17 show channel selection respectively performed onthe RS and data for antenna port #1 only, the RS-data separate channelselection can be performed for all antennas as shown in Table 18.

In Tables 16, 17 and 18, positions of Ch0, Ch2 and Ch3 can be limitedsuch that Ch0 and Ch1 correspond to the same PRB and Ch2 and Ch3correspond to the same PRB. As described above, when an RS part and adata part are separated from each other and channel selection isrespectively performed on the RS part and data part, it is advantageousto allocate corresponding channels to the same PRB such that an RS-datapair undergoes the same channel. When cross-carrier scheduling is used,channels (or resources) Ch0 and Ch1 obtained according to LTE-A FDDchannel selection are present in the same PRB and Ch2 and Ch3 arepresent in the same PRB, and thus the present invention is easilyapplicable. In the case of non-cross-carrier scheduling, Ch0 and Ch1 canbe present in the same PRB, and Ch2 and Ch3 can be present in the samePRB through explicit resource allocation. Here, for application ofsingle antenna (port) fallback, which will be described later, a mappingtable for single antenna (port) transmission and a mapping table for anantenna (port) for multi-antenna (port) transmission preferably havenested property.

Table 19 shows application of the transmit diversity scheme according tothe present invention on the basis of the mapping table (A=4) for CA FDDchannel selection, listed in Table 8. Referring to Table 19, RS-to-datamapping is applied to antenna port #0 (Table 8) as in the conventionalscheme and RS-data separate channel selection according to the presentinvention is applied to antenna port #1.

FIG. 13 shows a simulation result showing performances of the proposedscheme according to the present invention, single antenna transmissionand SORTD to which Table 19 is applied. Simulation was performed on theassumption that the number of receive (Rx) antennas is 2, normal CP isused, 3 km/h is applied to ETU channel model, a system bandwidth is 5MHz, and a joint ML (maximum likelihood) detector using both an RS anddata is used as a receiver algorithm. 4-bit A/N information transmissionperformances of the proposed scheme, single antenna transmission andSORTD were compared according to the simulation.

Table 22 lists required SNR and the number of resources used, whichsatisfy conditions of DTX→ACK error rate of 1% or lower, ACK→NACK errorrate of 1% or lower and NACK→ACK error rate of 0/1% or lower.

2Tx SORTD achieves 1.2 dB SNR gain as compared with 1Tx and the proposed2Tx scheme achieves 0.85 dB SNR gain as compared with 1Tx. However, 2TxSORTD requires 8 resources corresponding to twice the resources for 1Tx(100% additional overhead), whereas the proposed 2Tx scheme requires thesame overhead as that of 1Tx (0% additional overhead). Accordingly, thetransmit diversity scheme proposed by the present invention does notadditionally require resource overhead while having an SNR gaincorresponding to that of SORTD that achieves optimum performance.

Tables 23 and 24 show applications of the present invention.Specifically, Tables 23 and 24 respectively show applications of 2-bitA/N channel selection using 2 channels to FDD and TDD. Tables 23 and 24correspond to a case in which a single cell is configured and the DLbundling window is set to 2 (i.e. M=2) or a case in which two cells areconfigured and the DL bundling window is set to 1 (i.e. M=1).

Tables 19 and 21 (4-bit A/N) and Tables 25 and 26 (3-bit A/N) areformulated as follows. A resource used for an antenna port p is referredto as n_(PUCCH) ^((1,p)) and resources and information bits (beforemodulation) used for an RS part and a data part at antenna ports p=p0and p=p1 are defined as follows.

-   -   n_(PUCCH, RS) ^((1,p=p) ⁰ ⁾: (orthogonal) resource index of the        RS part for antenna port p0    -   n_(PUCCH, RS) ^((1,p=p) ¹ ⁾: (orthogonal) resource index of the        RS part for antenna port p1    -   n_(PUCCH, DATA) ^((1,p=p) ⁰ ⁾: (orthogonal) resource index of        the data part for antenna port p0    -   n_(PUCCH, DATA) ^((1,p=p) ¹ ⁾: (orthogonal) resource index of        the data part for antenna port p1    -   b^(p=p) ⁰ (0): 0-th information bit of the data part for antenna        port p0    -   b^(p=p) ⁰ (1): first information bit of the data part for        antenna port p0    -   b^(p=p) ¹ (0): 0-th information bit of the data part for antenna        port p1    -   b^(p=p) ¹ (1): first information bit of the data part for        antenna port p1

If an (orthogonal) resource index defined for single antennatransmission is n_(PUCCH) ⁽¹⁾ and the 0-th and first information bitsare b(0) and b(1), (orthogonal) resources and information bits selectedfor channel selection according to the present invention can berepresented as follows.n _(PUCCH,RS) ^((1,p=p) ⁰ ⁾ =n _(PUCCH) ⁽¹⁾n _(PUCCH,RS) ^((1,p=p) ¹ ⁾=(n _(PUCCH) ⁽¹⁾+α)mod(β) where α and β areintegersn _(PUCCH,DATA) ^((1,p=p) ⁰ ⁾ =n _(PUCCH) ⁽¹⁾n _(PUCCH,DATA) ^((1,p=p) ¹ ⁾ =n _(PUCCH,RS) ^((1,p=p) ¹ ⁾+γ where γ isan integerb ^(p=p) ⁰ (0)=b(0)b ^(p=p) ⁰ (1)=b(1)b ^(p=p) ¹ (0)=b(0)b ^(p=p) ¹ (1)=b(1)  [Equation 2]

Here, (A) mod (B) represents a remainder obtained by dividing A by B andn_(PUCCH) ⁽¹⁾+α refers to application of an offset to a PUCCH resourceindex (or PRB index, CS index and OCC index derived from the PUCCHresource index).

While it is assumed that b(0),b(1) modulated to data parts of antennas(antenna ports) have the same value, the present invention is applicableto a case in which modulation symbols have different values for antennas(antenna ports). In addition, the present invention includes applicationof the same rule to all slots or modification into slot-basedapplication (e.g. change of channels selected in first and second slotsand change of modulation symbols b(0),b(1), etc.).

In Equation 2, the RS resource index for the second antenna port isobtained by applying a predetermined offset to the resource index of thefirst antenna port and the data resource index for the second antennaport is derived from the second antenna port RS resource index, and viceversa as represented by Equation 3.n _(PUCCH,RS) ^((1,p=p) ⁰ ⁾ =n _(PUCCH) ⁽¹⁾n _(PUCCH,DATA) ^((1,p=p) ¹ ⁾=(n _(PUCCH) ⁽¹⁾+α)mod(β) where α and β areintegersn _(PUCCH,DATA) ^((1,p=p) ⁰ ⁾ =n _(PUCCH) ⁽¹⁾n _(PUCCH,RS) ^((1,p=p) ¹ ⁾ =n _(PUCCH,DATA) ^((1,p=p) ¹ ⁾+γ where γ isan integerb ^(p=p) ⁰ (0)=b(0)b ^(p=p) ⁰ (1)=b(1)b ^(p=p) ¹ (0)=b(0)b ^(p=p) ¹ (1)=b(1)  [Equation 3]

Unlike α in Equations 2 to 5, offset α can be used to indicate therelative order of a corresponding PUCCH resource from among given PUCCHresources. For example, if n_(PUCCH,i) ⁽¹⁾ indicates an i-th (0≦i<N)resource index from among N resources, the offset can be applied to i asrepresented by Equation 6.n _(PUCCH,RS) ^((1,p=p) ⁰ ⁾ =n _(PUCCH,RS,i) ^((1,p=p) ⁰ ⁾ =n _(PUCCH,i)⁽¹⁾n _(PUCCH,RS) ^((1,p=p) ¹ ⁾ =n _(PUCCH,RS,k) ^((1,p=p) ⁰ ⁾ =n _(PUCCH,k)⁽¹⁾ where k=i+α or k=(i+α)mod(β) and α and β are integersn _(PUCCH,DATA) ^((1,p=p) ⁰ ⁾ =n _(PUCCH,DATA,i) ^((1,p=p) ⁰ ⁾ =n_(PUCCH,i) ⁽¹⁾n _(PUCCH,DATA) ^((1,p=p) ¹ ⁾ =n _(PUCCH,DATA,m) ^((1,p=p) ¹ ⁾ =n_(PUCCH,RS,m) ^((1,p=p) ⁰ ⁾ where m=k+λ or m=(k+λ)mod(γ) and λ and γ areintegersb ^(p=p) ⁰ (0)=b(0)b ^(p=p) ⁰ (1)=b(1)b ^(p=p) ¹ (0)=b(0)b ^(p=p) ¹ (1)=b(1)  [Equation 6]

A description will be given of space-code block coding (SCBC) as amethod for enabling transmit diversity without doubling the number ofPUCCH resources. FIG. 14 illustrates a signal transmission method usingSCBC. Referring to FIG. 14, according to SCBC, space block coding isapplied between two (orthogonal) resources (e.g. PUCCH resources). Asillustrated in FIG. 14, SCBC can achieve transmit diversity using thesame (orthogonal) resources (e.g. Ch1 to Ch4) as those used for singleantenna transmission. To obtain a high spatial diversity gain, the two(orthogonal) resources to which SCBC is applied can be paired in thesame PRB or in PRBs close to each other.

The present invention proposes a resource allocation method for channelselection when the transmit diversity scheme is used. While a case inwhich a PDCCH corresponding to a PDSCH is transmitted along with thePDSCH for PDSCH transmission will now be described for convenience, thepresent invention can be equally applied to a case in which an SPS PDSCHwithout a PDCCH is transmitted and a case in which only a PDCCH such asan SPS release PDCCH is transmitted by applying the SPS PDSCH or SPSrelease PDCCH to a mapping table for channel selection. In addition,while two cells (i.e. PCell and SCell) (CCs) are configured in thefollowing description, the present invention is applicable to TDD inwhich one cell is configured. Accordingly, if cross-carrier schedulingis applied, a PDCCH corresponding to a PDSCH transmitted in the SCell istransmitted in the PCell and a PDCCH corresponding to a PDSCHtransmitted in the PCell is transmitted in the PCell. Whennon-cross-carrier scheduling is set, the PDCCH corresponding to thePDSCH transmitted in the SCell is transmitted in the SCell and the PDCCHcorresponding to the PDSCH transmitted in the PCell is transmitted inthe PCell.

Resource allocation for channel selection based on single antennatransmission in LTE-A is described first. Resource allocation forchannel selection is applied to both FDD and TDD, resource allocation ineach of FDD and TDD is divided into 2-bit, 3-bit and 4-bit A/Ntransmission cases, and each case is classified into cross-carrierscheduling case (CIF configuration) and non-cross-carrier-schedulingcase (no CIF configuration). For facilitation of description, in thecase of DL CC transmission modes 1, 2, 5, 6, and 7, a corresponding DLCC is regarded as being configured in SIMO (single input multipleoutput) transmission mode. In other transmission modes, a correspondingDL CC is regarded as being configured in MIMO transmission mode.

Conventional resource allocation for FDD channel selection is arrangedas follows.

-   -   2-bit A/N→2 (orthogonal) resources are needed (PCell-SIMO,        SCell-SIMO)    -   When a CIF is configured (i.e. cross-carrier scheduling)    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of a PDCCH corresponding to a PDSCH transmitted in the        PCell. For example, n_(PUCCH,0) ⁽¹⁾=n_(CCE,0)+N_(PUCCH) ⁽¹⁾.    -   n_(PUCCH,1) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,1) of a PDCCH corresponding to a PDSCH transmitted in the        SCell. For example, n_(PUCCH,0) ⁽¹⁾=n_(CCE,0)+N_(PUCCH) ⁽¹⁾.    -   When the CIF is not configured (i.e. non-cross-carrier        scheduling)    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of the PDCCH corresponding to the PDSCH transmitted in        the PCell. For example, n_(PUCCH,0) ⁽¹⁾=n_(CCE,0)+N_(PUCCH) ⁽¹⁾.    -   n_(PUCCH,1) ⁽¹⁾: 4 resource values (e.g. PUCCH resource values)        are configured by a higher layer for a UE and a resource value        indicated by a TPC field in the PDCCH corresponding to the PDSCH        transmitted in the SCell is used. The indicated resource value        is mapped to a resource.

3-bit A/N→3 (orthogonal) resources are needed (PCell-MIMO, SCell-SIMO;or PCell-SIMO, SCell-MIMO)

-   -   When the CIF is configured    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of a PDCCH corresponding to a PDSCH transmitted in a        serving cell configured in MIMO mode. For example, n_(PUCCH,1)        ⁽¹⁾: This is determined by n_(PUCCH,1) ⁽¹⁾=n_(PUCCH,0) ⁽¹⁾+1,        for example (i.e. resource immediately following the resource        linked to the lowest CCE index). In this case, the corresponding        resource is determined by (lowest CCE index of the PDCCH        corresponding to the PDSCH transmitted in the serving cell        configured in MIMO mode)+1.    -   n_(PUCCH,2) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,1) of a PDCCH corresponding to a PDSCH transmitted in a        serving cell configured in SIMO mode. For example, n_(PUCCH,2)        ⁽¹⁾=n_(CCE,1)+N_(PUCCH) ⁽¹⁾.    -   In the case of no CIF, PCell-MIMO and SCell-SIMO    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of the PDCCH corresponding to the PDSCH transmitted in        the serving cell configured in MIMO mode. For example,        n_(PUCCH,0) ⁽¹⁾=n_(CCE,0)+N_(PUCCH) ⁽¹⁾.    -   n_(PUCCH,1) ⁽¹⁾: This is determined by n_(PUCCH,1)        ⁽¹⁾=n_(PUCCH,0) ⁽¹⁾+1 for example (i.e. resource immediately        following the resource linked to the lowest CCE index). In this        case, the corresponding resource is determined by (lowest CCE        index of the PDCCH corresponding to the PDSCH transmitted in the        serving cell configured in MIMO mode)+1.    -   n_(PUCCH,2) ⁽¹⁾: 4 resource values (e.g. PUCCH resource values)        are configured by a higher layer for a UE and a resource value        indicated by the TPC field in the PDCCH corresponding to the        PDSCH transmitted in the SCell is used. The indicated resource        value is mapped to resource n_(PUCCH,2) ⁽¹⁾.    -   In the case of no CIF, PCell-SIMO and SCell-MIMO    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of a PDCCH corresponding to a PDSCH transmitted in a        serving cell configured in SIMO mode. For example, n_(PUCCH,0)        ⁽¹⁾=n_(CCE,0) ⁽¹⁾.    -   n_(PUCCH,1) ⁽¹⁾, n_(PUCCH,2) ⁽¹⁾: 4 resource values (e.g. PUCCH        resource values) are configured by a higher layer for a UE and a        resource value indicated by the TPC field in the PDCCH        corresponding to the PDSCH transmitted in the SCell is used. The        indicated resource value is mapped to two resources n_(PUCCH,1)        ⁽¹⁾ and n_(PUCCH,2) ⁽¹⁾.    -   4-bit A/N→4 (orthogonal) resources are needed (PCell-MIMO,        SCell-MIMO)    -   When the CIF is configured    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of the PDCCH corresponding to the PDSCH transmitted in        the PCell. For example, n_(PUCCH,0) ⁽¹⁾=n_(CCE,0)+N_(PUCCH) ⁽¹⁾.    -   n_(PUCCH,1) ⁽¹⁾: This determined by n_(PUCCH,1) ⁽¹⁾=n_(PUCCH,0)        ⁽¹⁾+1, for example (i.e. resource immediately following the        resource linked to the lowest CCE index). In this case, the        corresponding resource is determined by (lowest CCE index of the        PDCCH corresponding to the PDSCH transmitted in the PCell)+1.    -   n_(PUCCH,2) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,1) of the PDCCH corresponding to the PDSCH transmitted in        the SCell. For example, n_(PUCCH,2) ⁽¹⁾=n_(CCE,1)+N_(PUCCH) ⁽¹⁾.    -   n_(PUCCH,3) ⁽¹⁾: This is determined by n_(PUCCH,3)        ⁽¹⁾=n_(PUCCH,2) ⁽¹⁾+1, for example (i.e. resource immediately        following the resource linked to the lowest CCE index). In this        case, the corresponding resource is determined by (lowest CCE        index of the PDCCH corresponding to the PDSCH transmitted in the        SCell)+1.    -   When the CIF is not configured    -   n_(PUCCH,0) ⁽¹⁾: This is determined by the lowest CCE index        n_(CCE,0) of the PDCCH corresponding to the PDSCH transmitted in        the PCell. For example, n_(PUCCH,0) ⁽¹⁾=n_(CCE,0)+N_(PUCCH) ⁽¹⁾.    -   n_(PUCCH,1) ⁽¹⁾: This is determined by n_(PUCCH,1)        ⁽¹⁾=n_(PUCCH,0) ⁽¹⁾+1, for example (i.e. resource immediately        following the resource linked to the lowest CCE index). In this        case, the corresponding resource is determined by (lowest CCE        index of the PDCCH corresponding to the PDSCH transmitted in the        PCell)+1.    -   n_(PUCCH,2) ⁽¹⁾, n_(PUCCH,3) ⁽¹⁾: 4 resource values (e.g. PUCCH        resource values) are configured by a higher layer for a UE and a        resource value indicated by the TPC field in the PDCCH        corresponding to the PDSCH transmitted in the SCell is used. The        indicated resource value is mapped to two resources n_(PUCCH,2)        ⁽¹⁾ and n_(PUCCH,3) ⁽¹⁾.

Conventional resource allocation for TDD channel selection is arrangedas follows.

-   -   Single cell configuration    -   A PUCCH resource index is determined by the lowest CCE index        n_(CCE) of the PDCCH in each DL subframe within a DL bundling        window (i.e. M DL subframes).    -   Case in which two cells are configured    -   When a PDCCH is transmitted on the PCell    -   The PUCCH resource index is determined by the lowest CCE index        or (lowest CCE index)+1 (as necessary).    -   The PUCCH resource index is determined by the lowest CCE index        (n_(CCE,m=0)) of a PDCCH with DAI=1 and the lowest CCE index        (n_(CCE,m=1)) of a PDCCH with DAI=2 (when M=3 or 4, time domain        bundled channel selection mode is applicable).    -   When a PDCCH is transmitted on the SCell    -   4 resource values (e.g. PUCCH resource values) are configured by        a higher layer for a UE and a resource value indicated by the        TPC field in the PDCCH transmitted in the SCell is used        (non-cross-carrier scheduling).

In the above-described resource allocation scheme, when the firstresource is determined as n_(PUCCH,i) ⁽¹⁾=n_(CCE,i)+N_(PUCCH) ⁽¹⁾ tocorrespond to the lowest CCE index of the PDCCH and the second resourceis determined as n_(PUCCH,i+1) ⁽¹⁾=n_(PUCCH,i) ⁽¹⁾+1, the resources canbe efficiently used. For example, when the CCE aggregation level for thePDCCH is 2 or higher, an (orthogonal) resource corresponding to the(lowest CCE index)+1 is not used and thus more resources can be usedwithout additional overhead.

Use of an (orthogonal) resource corresponding to the (lowest CCE indexof the PDCCH)+1 as a transmission resource for an additional antenna(port) can be considered even when transmit diversity transmission isperformed. However, the (orthogonal) resource corresponding to the(lowest CCE index of the PDCCH)+1 is not always used for transmitdiversity. That is, an additional resource for multi-antennatransmission cannot be obtained through the method illustrated in FIG.15 (i.e. the PUCCH resource corresponding to n_(CCE)+1 is used for otherpurposes (e.g. channel selection, etc.)) (1) or can be given as a PUCCHresource corresponding to n_(CCE)+1 (2) while resources for singleantenna transmission are present. Here, (1) may correspond to a case inwhich PUCCH resources corresponding to n_(CCE) and n_(CCE)+1 are used bya different UE due to PDCCHs (including cross-carrier scheduling case)transmitted on the PCell or TPC fields in PDCCHs transmitted on theSCell indicate the PUCCH resources corresponding to n_(CCE) andn_(CCE)+1.

Considering the above description, the present invention applies theproposed transmit diversity scheme (refer to FIG. 12) or SCBC to thecase of (1) without additional resource allocation and applies SORTD tothe case of (2) using additional resources. That is, transmit diversityapplied to channel selection can be variably operated according towhether or not the lowest CCE index+1 (or PUCCH resource correspondingthereto) can be used as an additional resource for transmit diversity.For example, SORTD can be applied when the number of resources formulti-antenna (e.g. N Tx) transmission is N times the number ofresources for single antenna transmission whereas the transmit diversityscheme (refer to FIG. 12) proposed by the present invention or SCBC canbe applied when the number of resources for multi-antenna transmissionis less than N times the number of resources for single antennatransmission.

The multi-antenna transmission scheme can be operated as follows.However, the present invention is not limited thereto. In the following,underlined resources denote resources additionally allocated formulti-antenna transmission.

On the assumption that two cells are configured and cross-carrierscheduling is used in FDD, 4 (orthogonal) resources for 4-bit A/Ntransmission can be given as follows.

-   -   n0: a resource is determined by the lowest CCE index of PDCCH        corresponding to PCell PDSCH.    -   n1: a resource is determined by (the lowest CCE index of PDCCH        corresponding to PCell PDSCH)+1.    -   n2: a resource is determined by the lowest CCE index of PDCCH        corresponding to SCell PDSCH.    -   n3: a resource is determined by (the lowest CCE index of PDCCH        corresponding to SCell PDSCH)+1.

When the UE fails to decode the SCell PDCCH although the BS hasscheduled the two cells, the UE generates DTX for SCell ACK/NACK. Inthis case, a problem may be encountered when the transmit diversity(TxD) scheme of the present invention is applied since the UE cannotsecure two resources (n2 and n3) derived from the CCE index of the SCellPDCCH.

To solve this problem, the present invention proposes the following.

According to the first scheme, the UE can transmit A/N using theconventional single antenna port scheme when the UE cannot be aware ofresources that need to be secured while transmit diversity has beenconfigured. For example, when transmit diversity is configured for theUE, the following cases can be considered if 4 resources need to besecured for 4-bit A/N transmission in the above-described FDD example(i.e. two cells are configured and cross-carrier scheduling is applied).

-   -   Case in which both the PCell PDCCH and SCell PDCCH are        successfully detected    -   The UE transmits A/N using the TxD scheme since the UE can        secure all 4 resources.    -   Case in which the PCell PDCCH is successfully detected whereas        the SCell PDCCH is not detected    -   The UE uses the single antenna port scheme since the UE can be        aware of n0 and n1 but cannot recognize n2 and n3.    -   Case in which the PCell PDCCH is not detected whereas the SCell        PDCCH is successfully detected    -   The UE uses the single antenna port scheme since the UE can be        aware of n2 and n3 but cannot recognize n0 and n1.    -   Case in which both the PCell PDCCH and SCell PDCCH are not        detected    -   No transmission is performed since the UE cannot be aware of any        resource.

When the present invention is applied as described above, it is possibleto determine whether a specific cell corresponds to DTX according toreceiver (e.g. BS) implementation method to perform PDCCH linkadaptation (e.g. CCE aggregation level adjustment, PDCCH power control,etc.).

1) When the receiver always performs decoding on the assumption that 2Txis performed

A. A/N information can be acquired even when decoding is performed onthis assumption since the mapping tables for channel selection, proposedby the present invention, have nested property.

2) When the receiver performs blind decoding for both 1 Tx and 2Tx

A. A/N information can be acquired. However, it is difficult todiscriminate DTX from NACK as described below because DTX and NACK areinterchangeably used in the mapping tables.

i. In the case of detection on the assumption that 1Tx is performed: thereceiver can determine that DTX is generated for a specific cell forwhich NACK and NACK are fed back.

ii. In the case of detection on the assumption that 2Tx is performed:the receiver can determine that DTX is not generated for a specific cellfor which NACK and NACK are fed back.

According to the second scheme, N resources can be pre-configured by ahigher layer (e.g. RRC) in case the UE cannot detect a resource. Here, Nmay be the maximum value (or minimum value) from among the numbers ofresources that need to be acquired by the two cells (PCell and SCell).For example, if the PCell is MIMO cell, the SCell is SIMO cell and 3-bitA/N including 2-bit A/N transmitted for the PCell and 1-bit A/Ntransmitted for the SCell needs to be transmitted, 3 resources (two forthe PCell and one for the SCell) are needed. In this case, the number ofresources additionally configured may be 2 when the maximum value ruleis applied. In the case of 4-bit A/N, N may be 2 since 2 (orthogonal)resources need to be secured from each cell.

An (orthogonal) resource additionally configured by a higher layer canreplace an unobtained resource in a mapping table for channel selection.For example, if 2 explicit RRC resources (e.g. n⁽¹⁾ _(PUCCH,4) and n⁽¹⁾_(PUCCH,5)) are configured and a PDCCH with respect to the SCell ismissed, the UE can replace n⁽¹⁾ _(PUCCH,2) by n⁽¹⁾ _(PUCCH,4) andreplace n⁽¹⁾ _(PUCCH,3) by n⁽¹⁾ _(PUCCH,5) in Table 19. Accordingly,spatial diversity gain can be obtained even if resources are notobtained because the PDCCH is missed. Furthermore, when signals arereceived through n⁽¹⁾ _(PUCCH,2) or n⁽¹⁾ _(PUCCH,3), the receiver can beaware that A/N information is NACK when the A/N information correspondsto (NACK, NACK). When signals are received through n⁽¹⁾ _(PUCCH,4) orn⁽¹⁾ _(PUCCH,5), the receiver can be aware that A/N information (NACK,NACK) corresponds to DTX for the corresponding cell.

Alternatively, when it is assumed that non-cross-carrier scheduling, FDDand 4-bit A/N are used, resources indicated by the TPC field in theSCell PDCCH from among resource sets configured by RRC are used as 2resources for the SCell and thus the UE cannot obtain the resources ifthe UE misses the SCell PDCCH. Accordingly, the present scheme may beapplied to obtain a gain even in the case of non-cross-carrierscheduling.

The TxD scheme proposed by the present invention can be furtheroptimized in association with conventional resource allocation schemes.For example, a TxD mapping table can be designed using availableresources considering PDCCH missing. In this case, a predefined mappingtable can be used for antenna port #0 and an available resource can bemapped to antenna port #1 in consideration of PDCCH missing. Forexample, when 4-bit FDD A/N corresponds to (B, B, D, D) (B representingA or N except for DTX), resources Ch1 and Ch2 obtained from the PDCCH ofthe PCell are available whereas resources Ch3 and Ch4 obtained(implicitly or explicitly by ARI) from the PDCCH of the SCell are notavailable. In this case, Ch1 can be mapped to antenna port #0 and Ch2can be mapped to antenna port #1 (similar to SORTD) according to theconventional 1Tx mapping scheme. In the case of (A, D, A, D), (A, D, D,A), (D, A, A, D) or (D, A, D, A), all resources Ch1, Ch2, Ch3 and Ch4are available and thus mapping tables can be designed with an RS partand a data part separated from each other. Even in this case, transmitdiversity gain can be obtained without codeword overlap since allcodewords are discriminated.

While FDD mapping tables are described in the following for convenience,mapping tables described below can be used for TDD channel selection.

Table 27 shows application of the present invention to an FDD 4-bit A/Nmapping table. In Table 27, unshaded portions (rows 0, 1, 2, 4, 5, 6, 8,9 and 10) correspond to a case in which an RS and data can be separatedfrom each other even if a PDCCH is missed during resource allocation andshaded portions (rows 3, 7 and 11 to 16) correspond to a case in whichthere is a problem in resource allocation when the PDCCH is missed. Thisexample illustrates a case in which the RS and data are separatelymapped to antenna port #1 in the unshaded portions and SORTD is appliedto the shaded portions.

In this case, resource application can be performed as follows.

-   -   (Ch1=n_(PUCCH,0) ⁽¹⁾, Ch2=n_(PUCCH,1) ⁽¹⁾, Ch3=n_(PUCCH,2) ⁽¹⁾        and Ch4=n_(PUCCH,3) ⁽¹⁾).    -   In the case of cross-carrier scheduling    -   Ch1 and Ch2 inferred from the PCell are determined by n_(CCE)        and n_(CCE)+1 of the PDCCH (transmitted in the PCell)        corresponding to the PCell PDSCH.    -   Ch3 and Ch4 inferred from the SCell are determined by n_(CCE)        and n_(CCE)+1 of the PDCCH (transmitted in the PCell)        corresponding to the SCell PDSCH.    -   In the case of non-cross-carrier scheduling    -   Ch1 and Ch2 inferred from the PCell are determined by n_(CCE)        and n_(CCE)+1 of the PDCCH (transmitted in the PCell)        corresponding to the PCell PDSCH.    -   Ch3 and Ch4 inferred from the SCell are determined by resource        values indicated by ARI (TPC field) of the PDCCH (transmitted in        the SCell) corresponding to the SCell PDSCH.

Table 27 shows FDD 4-bit mapping table according to the presentinvention, which corresponds to a case in which the PCell corresponds toa MIMO cell and the SCell corresponds to a SIMO cell.

Tables 28 and 29 show FDD 3-bit mapping tables according to the presentinvention. Table 28 shows a case in which the PCell corresponds to aMIMO cell and the SCell corresponds to a SIMO cell and Table 29 shows acase in which the PCell corresponds to a SIMO cell and the SCellcorresponds to a MIMO cell. In Tables 28 and 29, unshaded portions (rows0, 1 and 2) correspond to a case in which an RS and data can beseparated from each other even if a PDCCH is missed during resourceallocation and shaded portions (rows 3 to 9) correspond to a case inwhich there is a problem in resource allocation when the PDCCH ismissed. This example illustrates a case in which the RS and data areseparately mapped to antenna port #1 in the unshaded portions and SORTDis applied to the shaded portions. The same mapping table can begenerated in the two cases.

For Tables 28 and 29, resource allocation can be performed as follows(Ch1=n_(PUCCH,0) ⁽¹⁾, Ch2=n_(PUCCH,1) ⁽¹⁾, Ch3=n_(PUCCH,2) ⁽¹⁾ andCh4=n_(PUCCH,3) ⁽¹⁾). Underlined parts denote additionally allocatedresources.

Alternatively, the present invention proposes use of a differenttransmit diversity scheme for rows having a resource allocation problem.The following cases can be considered.

-   -   SORTD is used (FIG. 11 and Tables 27, 28 and 29)    -   SCBC is used (FIG. 14 and Tables 30, 31 and 32)→Resource        allocation can be performed in the same manner as illustrated        with reference to Tables 27, 28 and 29.    -   The single antenna port scheme is used (e.g. PVS (precoding        vector switching), CDD (cyclic delay diversity), antenna        selection, etc.) (Tables 33, 34 and 35)→Resource allocation can        be performed in the same manner as illustrated with reference to        Tables 27, 28 and 29.

Conventional LTE-A FDD mapping tables were designed to support2-codeword PCell fallback. That is, when only the PCell PDCCH isreceived, used resources and constellation have the same forms as thoseof PUCCH format 1b. Since the resource of the second antenna port forSORTD of PUCCH format 1b is defined by (resource index used for thefirst antenna port)+1, it is preferable to use SORTD when resources arenot available in order to maintain nested property, as described above.Here, to improve A/N performance, remapping of rows having no resourceallocation problem can be considered. In this case, in order to minimizemodification of the conventional mapping tables, SORTD mapping isperformed for rows (shaded portions) having trouble with resourceallocation and an RS can be separated from data additionally at antennaport #0 (p=0) for rows having no trouble with resource allocation (i.e.rows in which all resources are available) (unshaded portions). Here, asa separation rule, +1 (when data resource n_(PUCCH,i) ⁽¹⁾ iseven-numbered) or −1 (when data resource n_(PUCCH,i) ⁽¹⁾ isodd-numbered) is applicable to an RS resource in single antenna mappingtables (Tables 36, 38 and 40). Equivalently, +1 (when RS resourcen_(PUCCH,i) ⁽¹⁾ is even-numbered) or −1 (when RS resource n_(PUCCH,i)⁽¹⁾ is odd-numbered) is applicable to the data resource in mappingtables (Tables 37, 39 and 41). Here, the above-described methods can beused for resource allocation.

Table 36 shows an FDD 4-bit mapping table according to the presentinvention (PCell MIMO, SCell MIMO). This example shows a case in whichthe position of the RS resource is changed by +1 or −1 from the dataresource at antenna port #0 (p=0) when there is no problem in resourceallocation (i.e. in the case of unshaded portions). When there is aproblem in resource allocation (i.e. in the case of shaded portions),the RS resource and data resource are inferred from the same PUCCHresource index at each antenna port.

Alternatively, SORTD can be used for rows having trouble with resourceallocation and an RS and data can be separately mapped even at antennaport #0 (p=0) for rows having no trouble with resource allocation(Tables 43 and 44, 4-bit A/N; Tables 45 to 48, 3-bit A/N). Specifically,in the case of 4-bit A/N (Tables 43 and 44), SORTD is applicable topaired resources (Ch1-Ch2 and Ch3-Ch4) for rows 3, 7, 10, 11, 12, 13,14, 15 and 16 and n_(PUCCH,i,DATA) ^((1,p=p0))=n_(PUCCH,i) ⁽¹⁾,n_(PUCCH,i,RS) ^((1,p=p0))=n_(PUCCH,(i+(−1)) _(i) _(),DATA) ^((1,p=p0)),n_(PUCCH,i,DATA) ^((1,p=p1))=n_(PUCCH,mod(i+2,4),DATA) ^((1,p=p0) andn_(PUCCH,i,RS) ^((1,p=p1))=n_(PUCCH,(i+(−1)) _(i) _(),DATA) areapplicable to other rows. One of the above-described resource allocationmethods can be used. In the case of 3-bit A/N (Tables 45 to 48), rows 3,4, 5, 6, 7, 8 and 9 may have trouble with resource allocation.

For nested property with respect tounavailable resources (due to generation of DTX) and PUCCH format 1bSORTD (reconfiguration handling), SORTD transmission can be performedwhen only a PDCCH corresponding to one of the two cells is detected(i.e. available resources are limited). In the case of implicit resourceallocation, when the first resource for antenna port #0 (p=0) is n₁, thesecond resource for antenna port #1 (p=1) is n₁+1. Particularly, Table49 is designed such that even though all resources are available in row10, SORTD is employed for row 10 in order to secure a distance fromother codewords.
